Alien Champion's Bride - Alien Warrior Brides, #6

An alien champion meets a nerdy and sweet girl, but they have to stop his father from stealing her home. Alien Warrior Brides is a series of standalone stories with a connected universe. Each book can be read separately. Guaranteed HEA. No cliffhangers. No cheating. Expect lots of steam. Zhanshi is a sector local legend with a short social attention span and a growing boredom with brainless, vapid women (who used to be fun).
He's done with being a playboy. He has been coming into his own for some time now with no credit from his regularly condescending father. Being repeatedly shut down when he attempts to join the discussion table with his father's contemporaries, he is slowly realizing that his father does not plan to allow him any real power in the kingdom. Annaisha is a keen, selective, and vastly powerful woman. Usually quite able to run her planetoid retreat without a hitch, she has been noticing her droids coming down with an infection that matches very few documented droid sicknesses on the books.
It could ruin her business entirely, but more importantly all of the people she regularly helps with her retreat space would be lacking the high quality of therapeutic attention she has been providing since she took over the regular running of the planetoid for her uncle. Zhanshi's kingdom may be able to "help, " for a "price." She soon learns that his father, the king, intends for them to marry for his own nefarious reasons.
